What is the most suitable vessel to make perfect curd without any liquid in it? If that true that a clay vessel will be good for it because clay will absorb liquid and the remaining thing you get will be curd?
PS: this image is just for reference. As there were some misunderstanding regarding for what curd i was asking.
And the clay vessel i am talking about look like this(In india we call it "Kulhad") :
The slight ability of clay to soak up whey doesn't matter, you won't really notice much difference with it. Just use any vessel that is convenient - glass, metal, plastic, glazed or unglazed clay, other ceramics will all work.
If you want curd without whey, you have to use a method which produces less whey (usually, that needs slower fermentation at lower temperatures) and/or strain the curd. Do it in a cheesecloth overnight under its own weight, don't press it like paneer. The vessel is not important.
In principle, better isolation can give you more stable temperatures and thus ensure better fermantation, possibly giving you curd with less whey. In this sense, the thicker the walls and the less heat-conductive your vessel, the better for curd. This would be a reason to use clay, ceramics or glass. But it can be easily offset by using more isolation for your fermenting environment.
If you're going to use a clay dish to absorb the liquid, it has to be unglazed clay. The dish in your picture won't absorb anything. I would also wonder about how you get a clay (terracotta) dish clean if it has liquid (presumably whey) soaked in. It may be a traditional approach that works well for daily use but not occasional use.
